AI Technical Summary

Technical Problem

Traditional aluminum molten casting channels lack active heating, resulting in large temperature gradients that easily lead to defects such as oxide inclusions, cold shuts, and shrinkage cavities. Furthermore, aluminum molten cooling lumps adhere to the channel surface, affecting the flow of aluminum molten material and resulting in high replacement costs and low production efficiency.

Method used

A self-heating aluminum liquid casting channel is designed. By setting heating resistance wire and heat insulation cavity on the base, the channel is separated from the base for easy replacement and to maintain a stable aluminum liquid temperature.

Benefits of technology

Stable control of flow channel temperature was achieved, preventing aluminum liquid from solidifying, reducing replacement frequency and cost, and improving the fluidity of aluminum liquid and the quality of castings.
